Application and Grade of Gray Iron
Property: Gray cast iron has excellent cutting and machining performance, casting performance, magnetic permeability, good wear resistance, high compressive strength but with low toughness, no forgeability, poor weldability.
Application:
1. It is used to manufacture some simple castings that only bear light loads, such as covers, trays, oil pans, handwheels, hand frames, bottom plates, handles and ingot molds, blast furnace counterweights in steel processing equipment, heavy steel hammers, etc.
2. Suitable for manufacturing track plates, cylinder liners, pump bodies, valve bodies, gear boxes, gears, scribing plates, machine bed, column, cylinder and piston (steam) oil piston rings, pistons, etc.
3. It is suitable for the manufacture of castings that are subject to high exaggeration stress and require high airtightness, such as heavy machine bed, gears, cams, large engine crankshafts, cylinder blocks, high pressure cylinders, and rolling mill stands.
4. It is used to manufacture large-sized machines such as lathes, punching machines and other heavy machinery, rolling skateboards, rollers, coking columns, cylinder mixer rings, support wheel seats, etc.
